People have different susceptibilities to SARS-CoV-2, the virus behind the COVID-19 pandemic, and develop varying degrees of fever, fatigue, and breathing problems -- common symptoms of the illness. What might explain this variation? Scientists may have an answer to this mystery.

Scientists detail the structure of dumbbell-like sequences in DNA during interphase that suggest several unseen aspects of chromosome configuration and function.

Ancient embedded elements in our DNA from generations past can activate a powerful immune response to kill cancer cells like an infection.

Researchers have demonstrated that a new liquid biopsy approach overcomes traditional barriers to quickly and efficiently diagnose and monitor high-grade pediatric gliomas.

According to the Mayo Clinic, about 15% of couples are infertile, and male infertility plays a role in over one-third of these cases. Often, problems with sperm development are to blame. Now, researchers have found a way to deliver a protein important for sperm cell production directly to mouse testicles, where it restored normal sperm development and allowed previously infertile mice to father pups.

Some people love spicy food -- the hotter, the better. Others go out of their way to avoid the palate-singeing burn of capsaicin, the compound that gives chili peppers their kick. Now, researchers have developed a portable device (whimsically shaped like a chili pepper) that can reveal how much capsaicin a pepper contains, before biting into it.

Americans strongly reduced their visits to grocery stores, pharmacies, and transit stations following stay-at-home orders from mayors and governors earlier this year, but did not reduce their visits to parks and beaches.

A team of researchers has found that transcription factors have a tendency to bind strongly to 'mismatched' sections of DNA, i.e. sections of the genome that were not copied correctly. The strong binding of transcription factors to these mismatched sections of regulatory DNA might be a way in which random mutations become a problem that leads to disease, including cancer.

Babies born with a faulty maternal copy of the UBE3A gene will develop Angelman syndrome, a severe neurodevelopmental disorder with no cure and limited treatments. Now, for the first time, scientists show that gene editing and gene therapy techniques can be used to restore UBE3A in human neuron cultures and treat deficits in an animal model of Angelman syndrome.

New research shows a simple skin test can accurately identify Parkinson's disease, which could lead to earlier detection of the disease and better outcomes for patients. Currently, Parkinson's disease is diagnosed by clinical signs and symptoms but only definitively diagnosed at autopsy. The researchers conducted a blinded study of 50 skin samples using an assay originally designed to detect mad cow disease.

A peace sign from Martin Luther King, Jr, becomes a rude gesture; dolphins in Venice's Grand Canal - manipulated or mis-used images posted as truth. Researchers say image editing software is so common and easy to use, it has the power to re-imagine history. Even the White House is doing it and deadline-driven journalists lack the tools to tell the difference, especially when images come from social media.

Imagine a mobile phone charger that doesn't need a wireless or mains power source. Or a pacemaker with inbuilt organic energy sources within the human body. Researchers are picking up the challenge of 'scavenging' invisible power from low-frequency vibrations in the surrounding environment, including wind, air or even contact-separation energy (static electricity).

A recent study shows that cold ambient temperatures increase vitamin A levels in humans and mice. This helps convert 'bad' white adipose tissue into 'good' brown adipose tissue which stimulates fat burning and heat generation.

Research has revealed that Virtual Reality (VR) technology can have significant impact on the validity of remote health appointments for those with eating disorders, through a process called Virtual Reality Exposure Therapy (VRET).
